GINEMATOGBAPHIC VIEW-HEARING APPARATUQ Application filed June 13, 1927, Serial 110, 38,668, and in France July 81, 1926.

My invention relates to view taking appa ratuses comprising a front part containing the object glass or glasses and the film driv-- Y ing mechanism and a rear part adapted to be secured speedilyand easily on the front part and containing the reel holding box and the guides for the film in front of the view-taking aperture.

In'view of ensuring a proper mounting of such a paratuses such as that disclosed'in my copen U. S. application Ser. No. 95,416, filed on vided with a catch or guiding stud which normally engages a perforation'of the film so 5 as to secure it in a-give nfposition and when the front part is secured overthefrear part is forced backwards and releasesthefil Now my invention has for'zitsfobject a catch devicewhich causes the reel holding box to open automatically when the catch is-forced backwards provided the cover of the rear part is closed.

I have shown by way'of example on appended drawings two forms of execution of my invention. v c a h Fig. 1 is a viewof the rear part with the coveropen.

Figs. 2, 3, and 4 are viewsof the same box, the cover not beingtshown and its locking device only being shown, certain parts being shown in vertical cross-section by a plane passing through line 2-2 of Fig. 5. h

Fig. 5 is a plan yiew of the rear part of the apparatus with its cover closed the casing being shown in cross-section.

Fig. 6 shows a modified form of the invention. i

As may bereadily seen the film guiding channel is shown in cross section on Figs. '2, 3 and 5. 7

Figs. 7 and 8 illustrate diagrammatically two other modifications wherein the film reels are disposed in separate holders. ,The rear part of the apparatus 1 to which is secured the front part 2 containing as stated the object glass 0 and the film driving mechanism M is closed by a cover 3 (Fig. 1) provided with a bolting rod 4 adapted to be engaged by the stops 5 (Figs. 2 and 3) borne by part 1. A: lever pivotally secuged at 6 to Lg adapted to come into the path of the lever arch 17, 1926, the rear part is pro- -21 engages ,normally under the action of the the rod 4 shows alower hook shaped part 7 and a top part 8 slightly incurved in a direction opposed to that of part 7. A stop 9 borne by the rod 4, serves for. preventing an exaggerated forward movement of part 7 of the lever. I

Onthe rear part (Figs. 2, 3, 4) is mounted.

the reel holder 10 contaming the take-up and the feed reels. The holderfis closed by means of a sliding door 11 provided with a knob 12 arm 7 when the cover 3 is closed.

To the front of part 1 is disposed the iding channel 13 wherein the'film 14 is a apted to move when it is wound from hefeed reel over the take up reel which is d iven by the toothed drum-15 (Fig. 1).

A catch is pivotally secured to the axle .16 borne by the front of part 1 and is provided with an extension 17 bearing a pin 18 to which 7 is secured a spring 19 the other end of which is secured at 2,0 to the apparatus. 1 This catch, is provided with .two projections of unequal length 21 and 22 (Fig. 5), the longer of which (6 spring 19 a perforation of the film 14, whereas the shorter projection 22 is pushed backwards, when the front part 2 is fitted on the rear'part of the apparatus by a stud 23 borne by part 2, which stud makes the catch pivot and releases the film from the projection 21.

The working is the following: Before the front part is mounted on the rear part, the projection 21 engages the film. If the cover 3 is closed over part 1, the parts come into the position shown on Fig. 2 where the reel holder is closed. When the cover 3 is locked, the rod 4 slides together with lever 7, 8. The end of part 7 abuts against the knob 12 without raising it nor consequently opening the door 11. Part 8 comes into contact with the pin 18 on the catch (Fig. 3). Finally when the front part 2 is fitted on the rear part (Fig. 4) the stud 23 comes against the projection 22'whereby the catch is caused to pivot; Thereby the pin 18 bearing on the lever arm 8 makes it pivot so, that the other arm 7 lifts the knob 12 and opens the door 11'-of the reel holder. 7

As soon as the front-part is removed, the catch 17 pivots forwards under the action of 100 12 where Fig. 6 shows a modified form ofthe closure of the reel holder 10. The borders of the opening 24 for the filnr are lined with velvet 25 or similar material. The holder 10 is provided with a transverse slide 26 whereina rod 27 is adapted to move. This rod bears at its end a spindle 28' on which-is pivotally secured the roller 29 which may thus close the opening 24 of the holder. 1

The rod 27 is in contact with the ineurved end of a lever 31 pivoting round the spindle 31' and provided with a lateral projection 32.

The locking rod 4 of the cover of the rear part bears a wedge33 pivotally secured to the sp 1n dle 34 and provided with a conical extension the movements of which are limited by the v of the lever 31 without touching the latter. ath cover i l d d l k d a i dl b in the same direction.

stop 35.

Part 1 shows as in the precedent case a spindle 16 fort-he? pivoting catch which is provided with two projections of unequal length 21 and 22 and is subjected to theiaction of the spring 37; The film gate is shown diagrammatically at 38,

When the rod 4 is not in its locked position, the pointed end of the wedge 33 is disposed between the catch 36 and the arm 32 The rearward pivoting motion of the catch 36 could not be transmitted to the lever 31. On the-contrary if the rod 4 is .in its locked lower. position as shown on Fig. 6 the extension of the stud is disposed between the catch 36 and the arm- 32 along a section of the extension which allows it to be-substantially in contact with both said parts.

and acts throu 'h the wedge- 33 on part 32 which is causedto move backwards. This makes the arm 31 pivot round the spindle 31 and the'roller 29 is pushed backwards so as to allow the,film 14 to pass out of the holder. It. should be noted the two parts of the film moving outof and into the holder both bear on the roller 29 which they both set rotating Fig. 7 is a. modification of Fig. 6 showin thetake-up and for the feed films instead of a single holder asin the precedent case. The lever 31 is forked at 31', 31", so as to control simultaneouslythe. slides 27 and 27f, and

. ratus comprising S81 spindle,

When the stud 23 of the front part 2 of the apparatus comes against the-projection 22 the' catch 36 pivots cover in closing consequently the closing rollers 29', 29" for the holders 10 and 10";

'Similarly, Fig. 8' shows a modification of Fig. 2 wherein the lever 7 controls a slide 7 adapted to control simultaneously the doors 11 and 11"- of the two holders.

What I claim is: 1. A cinematographic view taking apparatus comprising a front part, a removable rear part adapted to be secured on said front whereby the front part of the apparatus is caused when fitted on the rear part to' press said stud out of the perforations of the film,-

and to cause ment. c.

2. A cinematographic view taking up aa front part, a removal le rear part adapted to be secured on said front part, and containing the reel holders, a cover for said rear part, a bolt adapted to lock said cover in closing position, a movable stud borne by the removablepa t and adapted to. engage the film per orations, a lever it to actuate the lever arrangeadapted to open the reel holders, means whereby the bolt for the cover sets said lever inoperative engagement with the stud when ing the stud, perpendicularly to its axis, a pro ection shorter than the stud borne by a projection borne by part of the apparatus and ada ted to ress th'efirst mentioned projection w en the ront part is fitted on the rear part and thereby to release the stud from the film perforations against the action of the spring and to make 1t actuate the lever.

A cinematographic view taking up aratus comprising a front part, a remova 10 rear partadapted to be secured on said front part and containing the reel holders, a cover for said rear part, a bolt adapted to lock said position, a spindle borne by and adapted to rock round its axis in the removable part, a stud borne by the spindle perpendicularly to its axis and adapted to engage the film perforations, a slide inside each film holder, a rod sliding in said slide,
